iStat Menus freezes in Mountain Lion

Is anyone else having trouble with iStat Menus in Mountain Lion? Ever since I upgraded, my iStat has been freezing randomly. It will sometimes freeze for hours and then unfreeze briefly and then freeze up again. I can tell because my clock has seconds turned on, and when I hover over the iStat Menu section of my menu bar, I get beachball.

I tried changing my clock/calendar so it's only the calendar icon and then adding my regular Mac clock and calendar back, and moving most of my regular system icons to the right of the iStat icons (e.g., WiFi, VPN, Time Machine, Sync, system clock/calendar), but they still freeze up when iStat does. The only icons that don't freeze are Dropbox and Clusters, which are to the left of iState, and Spotlight and the Notifications icon, which are to the right of iStat. The VPN icon used to be to the left, but I moved it to see if that would help; it didn't.

This is making me want to uninstall iStat Menus, which is a shame, because I loved the program until Mountain Lion hit. I used it every day.
